Praise for this book
This book provides an excellent practical overview of biogas extension programmes, discussing challenges faced in different parts of the world, and the initiation and management of implementation programmes. It provides a clear overview of how anaerobic digestion actually works, focusing on design aspects that will help the reader to select a digester design, set it up and keep it going. It deals with the equipment needed to use the gas, and the important issue of how to use the valuable bioslurry residue produced by the digestion process. The book is thorough and well written from a practical perspective. I highly recommend it to anyone interested in practical implementation of small-scale digesters in rural areas.
Jo Smith, Professor of soil organic matter and nutrient modelling, University of Aberdeen, UK
David Fulfords extensive knowledge of biogas through decades of work in the UK and particularly overseas has been brought into this excellent and timely book which is concerned with technical aspects of biogas use in rural communities.
Maria M. Vahdati is a lecturer in Renewable Energy at the University of Reading, UK.
Anyone involved in biogas work will treasure this book because it provides details of the science of biogas, implementation and management of biogas programmes. David Fulford once again helps us think more clearly about important issues in rural biogas implementation.

Small-scale Rural Biogas Programmes is an excellent update in the field of biogas, which is a potential source of fuel around us. It is a useful reading material for Students of Environmental Science, and a reliable reference for those beginning and running biogas programmes.

Contents
Dr David Fulford is in a unique position to write this book on biogas extension programmes. He was involved in the national biogas programme in Nepal, as part of the biogas team in Developing and Consulting Services (DCS) of United Mission to Nepal (UMN) under Sanfred Ruohoniemi. He and the rest of the team (Andrew Bulmer, John Finlay and Mamie Lau Wong) wrote an extended report for USAID, which was published by UMN (Biogas: Challenges and Experience from Nepal). He rewrote this report as a book ( Running a Biogas Programme: A handbook ), published by Practical Action Publishing (then Intermediate Technology Publishing) in 1988. After doing a PhD, he taught on an MSc course on renewable energy at the University of Reading. After leaving in 2007, he set up Kingdom Bioenergy Ltd (www.kingdombio.com) to do consulting work.
One consulting contract was as an assessor for Ashden (www.ashden.org), which enabled him to visit many renewable energy projects around the world, including several biogas extension programmes. He led a team that did a mid-term evaluation of the UNDP funded project in Nepal in 1990 that followed the one started under UMN and was on a team that evaluated the Nepal and Asia Biogas Programme run by SNV (Netherlands Development Organisation) in 2012.
David Fulford is a founding trustee of Foundation SKG Sangha (www.foundationskgsangha.org), a UK registered charitable company, set up with Vidya Sagar Devabhaktuni and Kiran Kumar Kudaravalli of SKG Sangha in Kolar, South India, to encourage biogas extension work.
